| ''The effects of additive outliers on stationarity tests: a monte carlo study'' |
| ( 2004, Vol. 3 No.16 ) |
| |
| |
| Monte Carlo simulations are used to study the size and power properties of two stationarity tests developed by Kwiatkowski et al. (1992) [KPSS] and Leybourne and McCabe (1994) [LMC] when the data contain additive outliers. We show that the KPSS tests are very robust to additive outliers whereas the LMC test exhibits size distorsions and loss of power. |
